The primary function of the proximal convoluted tubule is Group of answer choices absorption of ions, organic molecules, vitamins, and water. adjustment of urine volume in response to ADH and aldosterone. secretion of acids, ammonia, and drugs. actively pumping sodium ions and chloride ions out of the filtrate. filtration of anything small enough to pass through the filtration membrane.

tissue

explanation:

it is actually formed by geoup of cells which is tissue

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
